Specification of Letters Patent.

Patented Got. 9, 191'?.

Application led November 30, 1915. Serial No.l 64,236.

To all whom t may concern:

Be it known that I, ERNEST E. PRoULx, a citizen of the United States of America,

and 'resident ofWillimansett, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Antiskidding Devices, of

which the following is a full, clear, and eX- act description.

This invention relates to a device or appliance for a tire-provided wheel for the prevention of skidding, by failure of traction, on wet. and slippery, or on muddy roads.

' A particular object of the invention is vto provide an attachment or appliance of the character indicated in which the jointed parts composing the device are unlike, and to eliminate the inclusion of link-chains, and by the improved character thereof conduce to increased durability and length of wear ning of the vehicle will be centrifugally thrown for injurious elfects and annoyance, may be most easily and quickly accom- 4plished.

The invention is described in conjunction with the accompanying drawings and is Set forth in the claims.

In the drawings Figure 1 is a side elevation of a tire provided automobile wheel showing the "present improved device thereon.

Fig. 2 is a plan view, on a larger scale, of a sufficient portion of the anti-skidpattachment to show the detail structural character thereof. I.

Fig. 3 is a view showing the means of connection of one of the side members of the device taken as seen at a right angle .to the `representation thereof in Fig. 2.

Fig. 4 is a view of one element of a series las taken on line 4-4, Fig. 2, and

Fig. 5 is a like view as taken on line 5-5 I of Fig. 2.

In the drawings, A and A2 represent opposite attachment members so made as to form, in substance, rings or' bands to extend around the opposite sides of the wheel, preferably near the flanks of the tire or the wheel rim.

One or both of these side members is provided withy a device B for connecting the ends thereof and for making the same circularly continuous.

The side members include spaced metal rlng or eye members a w and connected twisted cables b b formed with end eyes al d which are interengaged with the rings a.

While the parts of the side member are to be adjoined and 'rendered continuous, one

of the rings a has an elongated link e connected therewith, and another adjacent ring a has a clevis or loop f connected therewith and which is pivoted thereto, the plates g g having hooks L formed at their inner edges 4 and adapted when the parts g g are swung "to coincidence to constitute closed eyesl for the detachable connection therein of the link e.

The aforementioned rings or eye members a are provided with diametrical fingers z' each having one end j integral with the ring and .haying its portion la adjacent the place of itsv integral connection `with the ring proper; bowed transversely or to one side from the plane of the ring and extended obliquely across such plane, and having its free end m terminating in slight separation from the opposite side portion of the ring as particularly shown in Fig. 4.

The members G of the device, arranged to cross from side to side over the tread of the 90, tire, conslst each of a pair of transversely arranged 'twisted wire cable sections o o having eyes t t and u u at their ends, the ones u u` at the `1adjacent ends of the cable sections being interengaged with each other,

while the outer eyes t of such sections have detachable connections with the bowed parts c of the said inger'si of the rings a.

The said cable sections 0' 0 have enlargements 'v o in the form of buttons or knobs 100 at either side of their interengaged eyes u u.

These buttons or knob forming enlargements-may be composed of split bulky rings of suitable metal as iron or steel with cene.

trial openings therethrough, and when, in the A manufacture of the parts theyr are brought to encircling relations to the twisted wire 1 cable sections, and caused to engage such sections by being subjected to heavy pressure.

. The wire cable ysections themselves afford good tractional'effects, increased, however, by the provision of the enlargements o fv.

In case `one or a few of the transverse members which are extended across the tread become broken s0 as to have a tendency to fly outwardly by a centrifugal force to rap'- lengths and likewise connect the cross members to the side members, and anti-skid means on each length of cable.

2. In an anti-skid device for tires, oppo- 5 lidly strike the mud guard, these broken parts site side members including attaching finmay be readily detached from their end connections with the side members, and either immediately replaced' or the but partially impaired device may be continued in use until a convenient time for the replacement.

I claim :-l

l. ln an anti-skid' device, opposite sidel members each consisting of rings connected by flexible connectors, and cross members connecting the side members and. each consisting'of a pair of cable lengths having terminal eyes that pivotally connect the gers, and cross members each comprising a pair of cables having interengaging eyes at their inner ends and eyes at their outer ends detachably engaged with the fingers of said side members.

presence of two subscribing witnesses.
